A man who made a terrorists' handbook using information from an al Qaida training manual will be sentenced today.

Terence Brown, 46, made CDs from his home in Whitworth Road, Portsmouth with instructions on how to build improvised explosive devices (IEDs) and included extracts from the Mujahideen Poisons Book.

He pleaded guilty to offences under the Terrorism Act in an earlier hearing at Winchester Crown Court.

Brown called the CDs the Anarchist Cookbook and sold them worldwide in yearly editions for 35 US dollars (£23) each. Later it became a double CD set.

Brown had a now-closed website called www.anarchist-cookbook.com where the CDs could be bought from 2003 until 2008.

The information could have helped people prepare and commit acts of terrorism.

The haul of terrorist information found by police was the largest ever found in the UK.

Brown made tens of thousands of pounds from the business, but he had no terrorist sympathies.

He is now broke and has county court judgments against him.

Brown pleaded guilty to seven counts of collecting information that could have been used to prepare or commit acts of terrorism. The maximum sentence for the offence is 10 years' imprisonment.

Two counts of recklessly disseminating the information and one count of transferring criminal property will lie on file.

He will be sentenced at Winchester Crown Court.
